Holy crap. I finally figured out how to make these Quantum3D Voodoo2 cards SLI like the reference ones!👀

Quantum3D Obsidian2 Voodoo2 fixed and upgraded!👀

All designed checked out electrically. Some minor dimension fix on the VGA input board but it's looking really nice.😌

Yesterday was PCB day again! This batch is all about those two Quantum3D Obsidian2 cards - to expand their functionalities or solve issues.🫠

Started to implement QLang - A custom C-Ish scripting language for Quantum3D. #gamedev #indiedev - attached image is a test script.

A very rare and phenomenal 3Dfx Voodoo card came in today: A Quantum3D 100 SB with six whole 3Dfx chips!

Huh, so it's not over yet with the Q3D Voodoo2 card!

I just discovered that it has a weird set of components, probably to deal with consumer displays instead of PC VGA. Mod info is updated to Wiki to restore the correct brightness!👀

Some registry hacks to make the SLI not look weird cuz this Quantum3D card is a weirdo.🤪

So for these Quantum3D Voodoo2 cards to SLI (if they decide to play nice with their own kind🤡), the cable is very different from a reference one. I will document the details when all the projects are verified.😌

Yeah neither did I. Quantum3D hardware is so hard to come by so my only exposure was like most people with a bog standard Voodoo. I learned a LOT making that video

Working on "Quantum3D" - This will be an open-source 3D engine/IDE. I use QT OpenSource for the IDE, and the 3D engine is completely new, built entirely using Vulkan. Here's a test image of it's PBR shader. #gamedev #indiedev

Commited new version with better browser, scene graph and scripting integrated. check the github wiki for full instructions on how to use. Still very early in, but decent progress. #gamedev #indiedev github.com/StarSignalAn...

Spent the last two days implementing Point light shadows into Quantum3D. Also added a simple content browser for adding 3D meshes to the test scene. Next up is adding support for multiple lights, not just 1. I just commited this new version. #gamedev #indiedev
December 15, 2025 at 10:24 AM
Added official QLang and Quantum 3D docs. Still very early in, but the engine/scripting language are running nicely. #gamedev #indiedev -

Spent the day adding a terrain system/editor to Quantum3D. #gamedev #indiedev - commiting new version now.

Here you go. It's a bunch of Voodoo1s. But if that's possible, it should also be possible for 2s.

My beloved Gauntlet Legends and Dark Legacy used Quantum3D Obsidan2 3dfx cards in their board set.

The boards are flakey as hell with more problems than I can count on both hands and feet, but boy is that a fun ass game to play with a few mates and a lot of beers.
